5 Claims.

The invention relates generally to valves and more particularly to avalve for controlling the flow of fluid and manually movable for openingand closing it.

The general object of the invention is to provide a valve which isextremely simple and inexpensive in construction and eiiicient inoperation.

Another object is to provide a valve having a spout which serves as ahandle for operating the valve.

A further object is to provide a valve having a spout serving as ahandle for opening and closing the valve and having yieldable means forsecurely holding the spout in its open and closed positions.

A specic object of the invention is to produce a novel valve in which aunitary element constituting both a valve member and a discharge spoutis provided with a continuous passage through the valve member and spoutwhich, by the shifting of said unitary element, is brought into and outof registry with a passage in the valve casing to control the flow offluid through the valve as a whole. A Other objects and advantages willbecome apparent from the following description taken in connection withthe accompanying drawing, in which:

' Figure 1 is a longitudinal sectional View of a valve embodying thefeatures of the invention and showing the valve in closed position.

Fig. 2 is a view similar to Fig. 1 but showing the Valve in the openposition.

Fig. 3 is an end View of the valve in closed position.

Figs. 4 and 5 are perspective views of parts of the device.

Fig. 6 is a View of an operating handle for the valve.

Fig. 7 is a longitudinal sectional View, similar to Fig. l, but of amodified form of valve.

VThe exemplary embodiment of the invention comprises generallyra hollowbody having a passage openinginto the interior thereof. Within thebodyis a spout comprising av valve portion, spherical in form, seated inthe opening of the passage, a gasket being interposed therebetween, thevalve portion being arranged to close off the passage.` Extending fromthe valve portion is a stem portion with a passage extending through thetwo portions Awhich is arranged to be brought into register with thepassage in the body on rotation of the spout to open the valve.4Resilient means is provided for holding the valve in its open orclosed-positions.

As shown in the drawing, the preferred form of the valve comprises abody i0 having an attaching portion such as an externally threaded stemI I. The external shape of the body is such that it may be readilygripped by a wrench or the like, the shape shown in the drawing beinghexagonal. The body is preferably cup-shaped and a passage I2 in thestem I I opens into the interior of the body.

Mounted within the body and extending therefrom is a spout, indicatedgenerally at I3, com- "35 prising a valve portion lei and a stem portionI5. The passage l2 in the body is round while the valve portion ifi ofthe spout is spherical with its center lying on the axis of the pass-ageI2 and is of slightly larger diameter than the passage I2 129? so thatthespherical portion may .be seated in the opening of the passage toform a closure therefor, an annular gasket I6 of Vleather or the likebeing interposed between the spherical portion and the body. Thus, theportion of the body 125i surrounding said opening, with the gasket I6,constitutes a valve seat. The stem portion I5 extends radially from thespherical portion I4, a notch Il being cut in the side wall of the bodyto receive the stem. The stem portion may be 21)". provided with anared'end I8. Extending through thetwo portions of the spout isa passageI9. To open the valve, the spout is adapted to be rotated within thebody about the center of the spherical portion to bring the .passage i9in register with 25 the passage I2 in the body. Thus, the valve may beopened or closed merely by turning the spout.

To retain the spout in the body and to hold the spherical portiontightly against the seat, resilient means is provided, which, in thepresent 30- instance comprises a spring washer 2D seated against ashoulder in the open end of the body and rigidly secured at itsperiphery as by peening the body at the periphery of the washer. TheWasher is also notched to conform with Vthe notch 35- I'I in the body,so that the stem may be rotated. To assist in assembling the device, thewasher 2i! is provided with a pair of indentations 2l which bear againstthe spherical portion of the valve to the left side of the center linethereof, 40 as viewed in Fig. 3, to hold the spherical portion firmlyseated in the body while the body is being peened over the periphery ofthe Washer.

To securely hold the valve in its closed or open positions, yieldablemeans is provided which 45 comprises, in the present instance, a splitring 22 made of spring material and seated against a shoulder cut in thebody inside of the washer 2B, with the split alined with the notch I'lin the body. The ends of the ring at the split are 5() provided with twocam surfaces 23 and 24 against which stem I5 bears to spread the ring asthe stem is moved Afrom one position to the other. Preferably, the camsurface 23, against which the,. stein,bears whenmovingrfrom closed toopen position, is small and abrupt so that considerable force isrequired t0 Open the ValVe, thus preventing accidental opening of thevalve. On the other hand, the lcam surface 24, against which the stembears when moving from open to closed position, may be larger to permitthe valve to be easily closed.

To hold the split in the ring 22 in alinement with the notch in thebody, the washer 20 is provided with a pair of indentations 25 adjacentthe notch in the washer, which abut against the cam surfaces 24.

The operating handle shown in Fig. 6 is pro-V vided so that the valve,when used ina position which may not be easily reached, such as whenused as a drain plug for the crank case of an automobile, may be easilyoperated. 'Ihe operating handle in the instance mentioned, issuiiciently long to extend under the automobile from the side thereofand is provided with two arms 26 and 21 at different angles to thehandle, either of which may be inserted into the spout to open or closethe valve.

In the modied form shown in Fig. 7, the structureof the body isgenerally the same as that shown in Figs. l, 2 and 3. The spout,however, is of the faucet type and comprises a curved stem 30 and aspherical valve portion 3| having a passage 32 at a right angle to thestem so that 25 the valve may be open when the stem is in the positionillustrated. If desired, the gasket between the spherical portion andthe spring ring may be omitted.

In operation, Fig. 1 shows the valve closed, since the passage I9 in thespout is out of register with passage I2 in the body, the sphericalportion of the spout completely closing oi the passage I2. To open thevalve, the stem I5 may be manually grasped, or a tool such as the rodshown in Fig. 6 inserted into the stem, and the stem turned downwardlyto bring the passage I9 in the spout into register with the passage I2in the body. The spring washer 29 retains the spherical portion firmlywithin the body in either position and the spring ring 22 yieldablyholds the valve against movement from one position to the other. Whenthe valve is opened, it will be noted that an' unobstructed passage isprovided permitting fluid to flow freely therethrough.

In Fig. 7, the valve is shown open. To close it,v the stem 30 is moveddownwardly to rotate the spherical portion and move the passage 32 outof register with the passage in the body.

From the above description, it will be apparent that I have provided avalve which is extremely simple and inexpensive to construct, and whichis eilcient in operation. The valve is operated merely by moving thespout through a small angle, and when open, a relatively largeunobstructed passage for the ow 'of fluid is provided. It is also firmlybut yieldably held in either its open or closed position.
